Panax Geothermal Limited is developing a geothermal resource in South Australia, the Limestone Coast Project, which is a conventional “hot aquifer” reservoir in a deep sedimentary basin. The initial development is the Pretty Hill Formation sandstones in the Penola Trough of the Otway Basin. The area is an exploited gas basin with modern 3D seismic and excellent existing petroleum well data cove...

The steel frames, which are composed of expanded-section columns and beams, have bigger moment-resisting capacity better structural stability. So that they broadly applied in multi-story structures low to medium seismic zones. However, the section is likely local buckling due its expanded sections, decreases structure ductility. To support application, how determine horizontal design load studi...

This series of experiments aims to characterize the cyclic behavior of cold-formed steel (CFS) stud-to-sheathing connections. This connection provides the key energy dissipating behavior in wood sheathed CFS shear walls, and provides bracing to the studs under gravity and out-of-plane loads. A simple testing rig is developed consisting of two CFS lipped channels facing toe-to-toe connected on t...

The objective of this paper is to assess the promise of a novel tool for structural safety decision-making in severe unforeseen hazards. A straightforward measure is put forth for measuring the intensity of unforeseen hazards: the number of connected members removed from a structure in a brittle fashion. The tool selected for assessing this severe demand is the reduction in the buckling load ca...

Reinforced concrete walls are commonly used as the primary lateral-force-resistingsystem for tall buildings. As the tools for conducting nonlinear response history analysis have improved and with the advent of performance-based seismic design, reinforced concrete walls and core walls are often employed as the only lateral-force-resisting-system. Proper modeling of the load versus deformation be...
